Newmarket’s wisest trainer, Sir Mark Prescott, once noted: ‘The greyhound is propelled through the pain barrier by its desire to sink its teeth into the tantalising white bunny tail ahead of it. Humans are driven through it by the desire for riches and stardom. But what’s in it for the racehorse?’ His words came to mind after Beat The Bank, owned by King Power Racing, the operation founded by the late Leicester City chairman Vichai Srivaddhanaprabha, and trained by Andrew Balding, won the Group 2 Summer Mile at Ascot on Saturday for a second year.
